y and HENRY L. WHITMAN. both of the city ofA Be it known that we, CHARLES E. WHITMAN St..Lonis, in the State of Missouri, have invented a certain new and useful Improvement in Friction Clutches and Brakes for Baling- Prsses, ofwhich the following is a full, clear,

and exact description, reference being had to the accompanying drawings, forming part of l ing the friction-pulley and brake.

line VIVI, Fig. 1I, this figure also showingn parts in top View. Fig. 1V is an elevation of the' friction-pulley, and Fig. V is a section through the sliding collar of the pulley and throughv the shaft, the pulley being shown in elevation. This section is taken on line VIII 1X, Fig. III. Fig. VI is a section taken en line VIII-11X, Fig. III, looking toward 'the machine. Fig. VII is adetail top view showl is a detail modiiication. Ourinvention consists in features of novelty hereinafter fully described, and pointed out in the claims." 1 l Referring tothe drawings, 1 represents the [frame ofthe press, 2 represents the driving- The pulshaft,and'3 apnlley on the shaft.

' ,ley (see Figs. 1I to VI, inclusive) consists of 'an outer rim, 4, held loosely on the shaft 2 by means of a' spider composed. of a hub, 5, and arm 6. This part of the; pulley is `loose' npon the shaft and is held thereon by means of a collar, 7. The driving-belt (notfshown) passes around this part of the4 pulley. liVithtwo parts, 8 9, the parts being separated, as shownat 10. One end of the part 9V of the I ring is secured to anarm, 11, on a hub or ring,

12, and'one end of the part 8 of the ring is securedto an arm, 13, of the hub or ring 12. It will'be'seen that one end of each part 8 9 is j free to be forced outward. This is shown most clearly in Figs. IV and V. The ring 89 may bear against the inner face of the part y4 of the Fig.

Fig. viii pulley, but l prefer to interpose a bushing or ring, 14, of wood or some other suitable material. This ring 14 would be made in two parts corresponding with the parts 8 and 9 of the inner ring. On the free end of the part 8 of the inner ring is a lug, 15, against which bears a corresponding lng, 16 on a lever, 17, pivv ote'd at 18 to the arm 11. On the free end of the part 9 of the ring is a lug, 19, against which bears a corresponding lug, 20, of a lever, 21, pivoted at 22 to the arm 13. Thefree end of the lever 17 is connected by a rod, 28, to a cured to the driving-shaft 2, (see 25, Fig. V,) and the collar 24 turns with it. The other endet the iriver-21 is connected by a rod, 25, to the collar 24 on the opposite side of the collar to the rod 23. The collar 24 may be moved from the position shown in dotted llines, Fig; III, to the position shown in full lines, and. vice versa. 'As itis movedfrom the position shown in dotted lines to the position shown in fuii lines, it will be understood that it will force the .free ends of the levers 17 and 21 outward. through means ofthe connecting rcds23 and 26. As it does this, the lugs 16 and' 29 bear against the lugs 15-and 19 and force the ring 8 9 (or the bushing 14, if it is need) into frictional contact with the part 4 of the pulley, thus causing the shaft 2 to be turned. As the sleeve 24 is moved in the other direction, the ring 8 9 (or the bushing 14). will be moved out of frictional contact with the part 4 of the pulley, and the part 4 of the pulley willbe allowed to turn on 'the shaft without rotatingthe latter. It will be understood that there is sufficient elasticity in the parts 8 9 of the ring to cause the parts to spread out against the part 4 of the pulley between their free ends and the points of connection with the arnis 11 and 13.

The "sleeve 24 is preferably operated or moved by means of a bell-crank lever, 30,qJiv-' oted at 31 to an arm, 32, secured to the frame 1 of the machine. (See Figs. II and III.)

Connected to the other end of the le- One end of the lever 30 is bifurcatcd, and hassliding collar, 24, itting over the hub or ring 12 ofthe arm 13..

It'wi'll be seen --that when the shaft-'is rocked to. gnov'e the lel ver 30 infthedjreetion 0f the arrow, Fig." III, -th'e collar24will be'foreed toward the driving'- pulley, and when the .lever is moved in the other direction the collar will be moved away from the driving-pulley'. The shaft 37 is operatedby means of levers 39 39%, one on each end of the shaft. The levers 39 39%L have eastings 40, by which they are secured to the shaft,

the casting `of lever 39 having notches on its inner face, 'which engage with teeth on the outer faces of the hub 36,'as shown at 42, Figs. IV and VII. By the use of these teeth the 1e-4 ver 39 may be adjusted to the most couvenend of the shaft 37 from the lever 39 is a hub, 43,- having a cam, 44, formed thereon, kwhich bears'against a brake-shoe, 45, pivoted at 46 to a casting, 47,`secured tothe frame 1 of the machine. rlhe cam is sho-wn most plainly in Fig. I. The casting 40 of the lever 395 at this end of the shaft 37 is connected to the hub-43 frictionpulley is released thebralre stops the' rotation of the drivingshaft. When the shaft 37 is moved in the other direction, the brake isremoved from th'e wheel 50 and the -frictionlpulleyis thrown into working position.

In Fig. VIII we have shown a. slight modification of the brake, which consists of a crank,

necting the crank to the shoe 45.

The rods 23 and 26 are made `adjustable to compensate for wear, and they are preferably made adjustable' by making each in two parts and left threads to receive nuts 23%. By turn- -ing the nuts the lengths of the rods will be adjusted, as stated.

`cuter surface of the wheel, it is evide-nt that ,the same could bear upon the inner surface or upon the edge of the wheel.
